VIC MW - Drainage - Primary Catchment (Polygon) 18/07/2002 - 13/04/2018

Area representing catchments of major watercourses such as the Yarra River and Maribyrnong River. A primary river catchment is a catchment area composed of a single river system (where that river system reaches a bay or coast), a closed basin or a group of streams composing a coastal drainage area. A primary river catchment can be simple, dealing with the water of one watercourse, or complex, having a number of internal sub-catchments contributing to the whole. The Primary River catchment layer contains areas delineated by the watershed (natural or constructed) of a primary river watercourse.

This dataset provides a consolidated and consistent set of drainage catchments covering the entire Port Phillip and Westernport catchment area (Melbourne Water's area of responsibility for waterways and drainage). The primary purpose of this layer is for the hydraulic modelling of catchments and waterways, and/or calculations.
